This valuable publication explains the findings of a major study that analyzed the impact of repair/rewinding on the energy efficiency of Premium Efficiency/IE3 electric motors. 这项研究是2003年一项研究的后续研究.

The 2019 study reaffirms the results of the 2003 study.

The Effect of Repair/Rewinding on Premium Efficiency/IE3 Motors摘要。
In response to various opinions about the feasibility of maintaining motor efficiency during repair, 包括更换定子绕组, the Electrical Apparatus Service Association (EASA) and the Association of Electrical and 机械师al Trades (AEMT) conducted two comprehensive rewind studies using third-party 测试ing laboratories.

第一项研究的结果, which were published in 2003 (see Part 2 on Page 2-1 of this document), clearly showed that the efficiency of energy efficient and IE2 motors ranging from 7.5 HP到200 HP (5.5 kW to 150 kW) can be maintained (and sometimes improved) if the stator is rewound using established good practice procedures.

The increasing use of premium efficient motors mandated by various countries led to a second rewind study in 2019, this time to determine if the efficiency of premium efficiency and IE3 motors can be maintained when they are rewound using the good practices described in the 2003 rewind study and ANSI / EASA AR100-2015: Recommended Practice for the Repair of Electrical Apparatus.

As with the 2003 study, the results of the 2019 rewind study that follow clearly show the 答案是肯定的–with the average efficiency change for the entire 测试 group falling within the range of accuracy for the 测试 method (± 0.2%). In several instances, motor efficiency actually improved.
